What would you recommend to see and/or do in Hawaii?

It's the ocean. There are so many different things to see. 

They do the traditional Hawaiian dances, feed you great food and then at the end do the fire dance. 

On the beach, on top of the mountain, while you eat dinner. 

They drive you to different snorkel locations, feed you breakfast and lunch and then drive you around the islands. 

And the boat is a lot smoother than you would imagine.

It's an island relax

Hawaii has many different landscapes.

Get into nature walk through the bamboo forest.

Or on top of a mountain. 

This is specifically Maui, but I'm sure each island has its own version. A long windy road that has lots of waterfalls and goes through the jungle. 

It was hard to find but they are there. 

Essentially caves that would act as passage ways for lava. Creepy, beautiful, otherworldly and then opens into the jungle. 

There are lots of banana bread stands and they are all good. 

Hawaii has Costco and Walmart so stock up. 24 water bottles. Rash guard shirt. Sunscreen. Snorkel gear, it is a Lot cheaper to buy than to rent. 

It is a U.S. National Park. They never disappoint. Another long windy road, but worth it. Sunrise or sunset.

I believe it is over 10,000 feet up. And it gets really cold up there so bring lots of blankets or a coat and pants. 

Again Maui specific. The ocean waves hit up against the rocks and the ocean water pressure builds up and then explodes through a hole in the rocks.

Oh and there are all the black crabs surrounding the area, I guess feeding off the ocean water minerals? Again lots of lava rocks

Hawaii has lots of good food. You can grab something at the grocery store and just have a picnic outside or eat at a few fancy restaurants.

The Pour House

Maui Burgers - takeout only 

The Four Seasons 

You get into a parachute and the boat pulls and it lifts you into the sky.

Hawaii has lots of great landscape, do a bike ride through one of 2 areas.

But be warned Hawaii is not flat there are some hills you might have to go up and down. 

Time for a hunt. 

Have a cocktail.

Watch a program.

Maybe more... 

Save up your money and stay in a nice hotel with a nice view. It is worth it.
